| class money_base; |
||
The class std::money_base provides constants which are inherited and used by the std::moneypunct, std::money_get and std::money_put facets.
Member types
| Member type | Definition |
| enum part { none, space, symbol, sign, value }; | unscoped enumeration type |
| struct pattern { char field[4]; }; | the monetary format type |
| Enumeration constant | Definition |
none
|
whitespace is permitted but not required except in the last position, where whitespace is not permitted |
space
|
one or more whitespace characters are required |
symbol
|
the sequence of characters returned by moneypunct::curr_symbol is required |
sign
|
the first of the characters returned by moneypunct::positive_sign or moneypunct::negative_sign is required |
value
|
the absolute numeric monetary value is required |
Notes
The monetary format is an array of four chars convertible to std::money_base::part. In that sequence, each of symbol, sign, and value appears exactly once, and either space or none appears in the remaining position. The value none, if present, is not first; the value space, if present, is neither first nor last.
The default format, returned by the standard specializations of std::moneypunct is {symbol, sign, none, value}.
